dividing a number

[alin19]

what is the comand to  eliminate the last number from a number

 

$a= $a /10?

 

and how i get that number that i took out?

 

$x=$a .... 10

 

 

why whis comand dosn't work?

 

  if (0.0101< $a<=0.2000)

{

}

[trq]

Sorry, your explination is not clear. What is it your after?

[asmith]

that would be % command :

 

$a = 26 % 10 // $a  =  6 
$a = 675 % 10 // $a = 5     

 

 

 

why whis comand dosn't work?

 

  if (0.0101< $a<=0.2000)

{

}

 

i don't think you could do whole in one that should be :

 

   if ( $a > 0.0101  &&  $a <= 0.2000)    //  $$ mean and , you can use  and too .
{
}

 

 

 

[alin19]

yes this is good,

 

but i need one more,

 

 

from 52  i need to get 50

 

from 58 also 50

 

[asmith]

i dont' know any function for that , BUT why don't you sub that number :

 

$a  =  52;

$b = $a % 10;

$c = $a - $b;     //  $c will be 50 . 

[alin19]

yes, i think that will work the same,

 

10x

[rajivgonsalves]

or

<?php

$a = 58;
echo ((int) ($a/10))*10;

?>

[alin19]

my numbers are in format 0.0000

 

 

 

4 zecimals not (INT)

[rajivgonsalves]

 

from 52  i need to get 50

 

from 58 also 50

 

 

if you give examples maybe I could fish something out

[alin19]

if (isset ($b))

{

if ($b=='rgbs' OR $b=='dlbs' || $b=='odbs' || $b=='xmbs' || $b=='xdeal' ||$b=='RGBS' || $b=='DLBS' || $b=='ODBS' || $b=='XMBS' || $b=='XDEAL' )

{

 

  if ($a<=0.0100)

{ 

         

                }

  if (0.0101< $a AND $a<= 0.2000)

{ 

 

$h=number_format($xmax % 10, 4, '.', '')

$xmax=number_format($xmax-$h; 4, '.', '')

 

 

 

                }

  if (0.2001<$a AND $a<=1.0000)

{ 

         

                }

  if (1.0001<$a AND $a<=5.0000)

{ 

         

                }

 

  if (5.0001<$a AND $a<=20.0000)

{ 

         

                }

  if (20.0000<$a)

{ 

         

                }

 

}

 

 

    }

 

 

this is what i have until now, it is complicated, not tehnical but work,

 

i will have 3 numbers, x xmin xmax, 

 

  xmin=x-15/100*x

  xmax=x+15/100*x

 

 

and those steps:   

x <0.0100        here x, xmin , xmax can grow with 0.0001

0.0101<x<0.2000  here x, xmin , xmax can grow with 0.0010

0.2001<x<1,0000  here x, xmin , xmax can grow with 0.0100

1.0001<x<5.0000  here x, xmin , xmax can grow with 0.0500

5.0001<x<20.0000  here x, xmin , xmax can grow with 0.1000

x<20.0000            here x, xmin , xmax can grow with 0.5000

 

 

the big problem is when for example

 

x= 0.1900

because xmax will go into the other step,

 

i'm working on it

 

 

 

[alin19]

if (0.0101< $a AND $a<= 0.2000)

{ 

 

$h=number_format($xmax % 10, 4, '.', '')

$xmax=number_format($xmax-$h; 4, '.', '')

 

 

    if ($xmax >0.2000)

{

      $h1=number_format($xmax % 10, 4, '.', '')

  $xmax=($xmax-$h1) /10

  $h2=number_format($xmax % 10, 4, '.', '')

  $xmax=(($xmax-$h2) /10)*100

 

 

}  

 

 

if ($xmin <= 0.101)

 

 

{

 

 

 

}

 

something like this i think it will work, still working on it

[alin19]

$a= 0.0501

$b=$a %10;

$c=$a-$b;

 

 

will this work if those won't be int numbers?

[alin19]

if (0.0101< $x AND $x<= 0.2000)

{ 

 

if ($xmax <= 0.2000)

{

$xmax=$xmax*10000;

$h=$xmax % 10;

$xmax=$xmax - $h;

$xmax=$xmax/10000;

$xmax= number_format($xmax, 4, '.', '');

}

 

 

if ($xmin >0.0101)

{

$xmin=$xmin*10000;

$j=$xmin % 10;

$xmin=$xmin-$j;

$xmin=$xmin/10000;

$xmin= number_format($xmin, 4, '.', '');

}  

 

    if ($xmax >0.2000)

{

 

  $xmax=$xmax*10000;

      $h1=$xmax % 10;

  $xmax=($xmax-$h1) /10;

  $h2=$xmax % 10;

  $xmax=(($xmax-$h2) /10)*100;

  $xmax=$xmax/10000;

  $xmax= number_format($xmax, 4, '.', '');

 

}  

 

 

if ($xmin <= 0.101)

 

 

{

}

 

}

 

i've done this;

 

when all of $x, $xmin and $xmax are between 0.0101 and 0.2000 all it's ok,

but when $x is  0.1900 i get:

MAX  0.2300  good

x 0.1900  good

MIN 0.1421  bad
